CICS/TS Performance and Tuning (CAE)

Course:  CAE
Duration:  4 Days
Level:  II
Course Summary

This course covers the performance aspects of a CICS/ESA system and how to measure and tune the system to meet performance objectives. The course material is reinforced with classroom examples and review of students' systems. The course concentrates on CICS/ ESA V4.1 with its changes and considerations. The course is also appropriate for CICS/ESA V3.1, V3.2 and V3.3.

What You Can Expect

After completion of this course, you should be able to:

  • Describe the elements of performance analysis and resource management
  • Understand methods used to measure and tune a CICS/ESA system
  • List resources used and managed by CICS/ESA and demonstrate methods used to minimize resource consumption
  • Obtain information about CICS/ESA resource utilization
  • Describe CICS/ESA V4.1 storage, task, file, and network management and how to monitor these functions
  • List performance considerations of the CICS DB2 and CICS DL/1 interfaces
  • Identify resource contention and proper use of tuning parameters to control contention
  • Understand performance considerations for interconnected CICS systems
Who Should Take This Course

This course is designed for system programmers/analysts responsible for installation, support, debugging, or performance of a CICS/ ESA system. Very experienced CICS application programmers wishing to gain knowledge on efficient use of CICS facilities will also benefit from this course.

Recommended Prerequisites

Before taking this course, you should have experience installing, tailoring, or maintaining a CICS/ESA (any release). If you are in the process of migrating to CICS/ESA, prior experience with CICS in an earlier version satisfies this prerequisite.

Training Style

Class consists of classroom lecture and lab sessions.
